The coronavirus disease 2019 (COVID-19) consistently displays a higher mortality in males. This sex-specific difference in outcomes is seen not only in the current COVID-19 pandemic, but also in prior viral epidemics and pandemics. Sex hormones, such as testosterone, play a clear role in modulating the immune response, providing a clue that may illuminate the underpinnings of these outcomes. Developing a deeper understanding of these epidemiological findings permits a more effective response to the disease. This article summarizes the sex-specific COVID-19 outcomes, the role of androgens in generating these outcomes, and the potential role of modifying testosterone levels as a form of treatment of COVID-19.
